To-day

Here hath been dawning another blue day:
Think, wilt thou let it slip useless away?
Out of Eternity this new day was born;
Into Eternity, at night, will return.
Behold it aforetime no eye ever did;
So soon it forever from all eyes is hid.
Here hath been dawning another blue day:
Think, wilt thou let it slip useless away?

— Thomas Carlyle
